+title: TrustMark watermarking
+---
+
+TrustMark is an open-source universal watermarking system for images that:  
+
+- Can encode, decode, and remove watermarks from images.
+- Works with arbitrary resolution images.
+- Has implementations in both Python (using PyTorch) and JavaScript (using ONNX).
+
+:::info
+For full technical details and help getting started with TrustMark, see [TrustMark - Quick start](trustmark/readme.md#quick-start).
+:::
+
+## Variants
+
+TrustMark has three primary model variants, each with different characteristics.
+
+Images encoded with one variant cannot be decoded with another variant, so you need to stick with the same variant throughout your pipeline.
+
+- **Variant Q (Default)** Use in most cases, where you want a good balance between robustness and imperceptibility.  PSNR is 48-50 dB.
+- **Variant P** - Use when image quality is the top priority. PSNR is 43-45 dB.
+- **Variant C (Compact)** - Use if you need to minimize model size and can live with slightly lower visual quality. PSNR is 38-39 dB.
+
+The general recommendation is to use either:
+- Variant Q for most use cases
+- Variant P when visual quality is paramount
+
+### About PSNR
+
+PSNR (Peak Signal-to-Noise Ratio) is a technical metric used to measure image quality, particularly when comparing an original image to a modified version (in this case, the watermarked image). PSNR is measured in decibels (dB), and higher values indicate better image quality:
+- Values around 40+ dB typically indicate very good quality
+- Values around 30 dB indicate acceptable quality
+- Values below 20 dB usually indicate poor quality
